Abstract
The invention discloses a resource and harmless processing method for biggest solid waste distiller's grain of traditional white spirit. The method comprises the following steps: adding diastatic enzyme, acid protease, thermostable active dry yeast, moderate-temperature yeast and cellulase into the distiller's grain of white spirit, and putting the mixture in a pit for solid state fermentation; adding rhizopus, red yeast, high-temperature yeast, distiller's grain wine and concentrated hexanoic acid fermentation liquid into the pit for solid-liquid combined fermentation; extracting and distilling the fermented grains to obtain natural essence for thick-flavor white spirit, natural essence for table vinegar and substance prepared into protein feed at the same time. The method disclosed by the invention has low cost, short production period, can process 35,000 tons of distiller's grain annually for the production scale of 8,000 t/a, reduces the pollutants CODcr, BOD5, SS and ammonia nitrogen discharged to environment, and plays a tremendous effect in the regional environmental protection. Meanwhile, the essence products prepared from the distiller's grain effectively improve the quality of white spirit and table vinegar, and sufficiently reflect the recycling value of the resource and harmless processing of solid waste of white spirit.
Description
Technical field
The present invention relates to a kind of brewed spirit recycling of solid wastes and harmless processing method, belong to the environmental protection field.
Background technology
We know that the production of conventional solid-state liquor is that a multistep is rapid, the process that the production cycle is long, and 1 ton of 60 former wine of degree of every output, there then have the 3-4 ton to lose to be poor.Owing to lose the strong suction-operated of precipitation, cellulose, hemicellulose in poor, water and many organic matters all be wrapped in lose poor in.Generally lose poor the stacking after 2 days, because air and action of microorganisms, a large amount of organic wastewaters ooze out, and its average CODcr is up to 5.65*10
5Mg/L.Generally speaking, middle-size and small-size wine industry will be lost to be pickled with grains or in wine and be sold when running up to some.Cause local water environment pollution inevitably losing in the poor holdup time.Large-scale wine enterprise all adopts and drops into environmental protection facility voluntarily and handle.
Owing in the spirit distiller grain, except that the flavor component that contains liquor, also be rich in starch, crude protein, crude fat, carbohydrate, cellulose, calcium, phosphorus, iron, amino acid, except that starch, high energy composition homogeneous phases such as crude protein, crude fat are similar to corn in dried being pickled with grains or in wine.Therefore, the domestic approach that utilizes to spirit distiller grain has following several mode:
1, produce high protein feed, the technology of taking is: lose poor → solid-liquid initial gross separation → drying (140 ~ 160 ℃) pulverizing → sale.In implementing dry run, generally use the hot blast drum drying machine, fluidized bed dryer or air-flowing type drying.This kind method also will be to the further biochemical treatment of isolated organic wastewater.In drying, many flavor components and organic matter are discharged, and cause air pollution.
2, produce biogas, adopting process is: lose poor → Separation of Solid and Liquid → poor liquid through anaerobism → anaerobic fermentation → biogas.Produce the mode of biogas and only utilized poor liquid, but residual poor slag still need handle, the cripple amount behind the biochemical biogas is big, and the CODcr after the processing also needs the secondary biochemical treatment could qualified discharge generally about 10000mgL.This method is disposable to have high input, the operating cost height.
3, it is fertile to make farming, and adopting process is: it is personal to lose poor → Separation of Solid and Liquid → mix pond sludge → peasant.Though can change barren soil clay structure, increase organic matter, improve land fertility, make agricultural produce, this method still drains into atmosphere with many organic matters.If be used for Edible Fungi, cultivate the environmental pollution that body also can cause the secondary solid discarded object, income is very little economically.
4, be used for aquaculture, will lose the poor heap fermentation after the acidity of suitably adjusting, allow can excite organic matter to discharge after, culture fly maggot, earthworm etc.Also have to utilize and lose the poor forage protein that extracts, produce processing methods such as glycerine.
More than these methods lose poor environmental pollution and have certain effect solving the wine brewing solid waste, but income is very little economically.And in the China that has the very huge liquor consumer group, accessory substance and discarded object by liquor self fermentation, produce fermented soy baste (natural essence), all will produce enormous function to social benefit and economic benefit undoubtedly, especially the maximum solid waste of liquor is lost poor method for innocent treatment and be there is no relevant report at present at home and abroad.
Summary of the invention
The object of the present invention is to provide the maximum solid waste of a kind of liquor to lose poor resource and method for innocent treatment, residual shallow lake during its utilization is lost and is pickled with grains or in wine, residual sugar, earlier through carbohydrase, cellulase, acid protease, high temperature resistant active dry yeast and daqu of middle temperature effect, carry out solid state fermentation, again by adding based on head mold, red colouring agent for food, also used as a Chinese medicine, high-temperature daqu is the compound esterification enzyme and the concentrated caproic acid fermentation liquid of assisting, carry out the solid-liquid combination fermentation, obtain containing abundant ester respectively, the aromatic Chinese spirit of local flavors such as aldehyde ketone with and vinegar with brewageing baste, residue can be made into protein feed, thereby reaches the purpose that the maximum solid waste of liquor is lost poor harmless treatment.
The objective of the invention is that following technical scheme realizes by implementing.
The maximum solid waste of a kind of liquor is lost poor resource and method for innocent treatment, it is characterized in that it is is raw material to lose poor, obtains aromatic Chinese spirit simultaneously and is used to make protein feed with natural essence, vinegar with natural essence and remaining residue by solid state fermentation, solid-liquid combination fermentation, extractive distillation:
